+This is a wrapper around a project called [`quadlet-nix`](https://github.com/SEIAROTg/quadlet-nix), a way of defining systemd services as containers with Nix! Since I have existing services running inside of containers and don't want to risk breaking _everything_ that I have running, I figured this would be a safe, transitionary approach to handle this.
